Grab hooks can securely hold onto a single link of chain to shorten a leg or create loops. The chain provides strength and ruggedness to withstand the harshest working conditions. Slings include a tag that shows chain grade and size, length, and capacities in each configuration.

Grade 100 steel slings are approximately 20% stronger than grade 80 steel.

Prevent accidental opening of the hook with these locking hooks. The chain provides strength and ruggedness to withstand harsh working conditions. Slings include a tag that shows chain grade and size, length, and capacities in each configuration.

Grade 100 steel slings are approximately 20% stronger than grade 80 steel.

Note: Do not use slings at an angle less than 30°.

Warning: Never use to lift people or items over people.

Safety Chains for Trailers

With Latch Hook

Keep trailers attached to their vehicles even when the hitch fails. Use chains in pairs. The maximum trailer weight per pair must meet or exceed maximum trailer weight. Maximum trailer weight is the total weight being towed.

Warning: Never use for lifting applications. See Chain—For Lifting.
